WILLIAM J. BACON, OF ADDISON, MICHIGAN.

FRUlTrDRlER.

SPECIFICATION forming part of Letters Patent No. 256,615, dated April18, 1882.

ApplicationfiledJulylB, 1881. (Mode-l.)

To all whom it may concern:

Be it known that I, WILLIAM J. Bacon, of Addison, in the county ofLenawee and State of Michigan, have invented certain new and usefulImprovements in Fruit-Driers; and I do hereby declare that-the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which formapart of this specification, and in which- Figure l is a side view of myimproved fruit-drier. Fig. 2 is a vertical longitudinal section, andFig. 3 is a vertical transverse section through line 00 m of Fig. 2.

This invention has reference to an improvement in fruit-driers, havingfor its object to effectively and properly dry or. cure the fruit; andit consists in the combination and arrangement of parts substantially ashereinafter more fully set forth.

In the accompanying drawings, A is a vault orinclosure,in whichis placedthe heater or furnace B.

O is a case or house, with its under forward end supported upon thevault or inclosure A of the furnace, while its rear end is supportedupon an upright frame or legs, a, supporting the case in an inclinedposition.

Arranged in the lower part of the case A are a number of heatingtubes'or flues, D .D,

connected to the furnace B and together at A number of cleats, d,extending the entire length and secured to the sides of the case 0 inthe same inclined plane with the case, afford means upon which to placethe fruittrays E, having gauze bottoms to permit the ready passagethrough them ofvthe steam or heat to the fruit to effect the drying ofthe fruit. I

To permit the escape of the vapor or steam, a pipe, 6, with openings orshort tubes e at certain intervals apart upon its lower side, is affixedto the inside of and has an elbow, e, passing up through the top of thecase 0.

At the ends and in the sides of case 0 are doors F to permit of thepassing into and the removal from the case of the trays of fruit. Thetrays of fruit are passed into the case at the lower end, the precedingtray being pushed along by the succeeding one until the ,hot-air exit 6will come into operation.

first inserted tray has reached the upper discharging end of the case,when its contents will have been properly and effectively dried, andconsequently in condition to be removed. This process is continued untilall the trays of fruit have been dried and removed.

By the construction of the drier as herein shown and described all partsof the apparatus are easily accessible. The heat within the casing isalways even and easily controlled; and by the arrangement of theinclined pipe c with its inlets c excess of hot air is carried off withthe vapors of the fruit in a gradual manner from the highest point ofthe inclined roof or top of easing 0 toward the lowest. This is becausethe hot air will naturally ascend from the top of the furnace A B andheating-fines D to the highest point or rearward upper corner of easingG, where it will accumulate until the level indicated by the broken linemarked e z is reached, when the surplus will escape through the upperoutlet 6 If there is an increase of heat, so that the upper opening 6 isinsufficient to carry off the excess, alower level, 2 2, will graduallybe reached, when, and not before, the second These two outlets will, asa rule, be found amply sufficient to carry off all moisture and excessof heat; but if in firing up or from other causes the heat in thefurnace should be further increased, the lower hot-air level, 2? 2 willbe reached, and the third or lowermost outlet 6 comes into play. In thismanner I am enabled to maintain a regular and even temperature withinthe apparatus, which is of the greatest importance in drying fruit.

Having thus described my improvement, I claim and desire to secure byLetters Patent of the United States- The combination, with the furnace AB and inclined casing 0, having flues D and trays E, arraugedasdescribed, of the inclined hot air exit -pipe 6, arranged under theinclined roof of the casing, and provided with a IOC) series of inlets,e e 0 and outlet 0, substantially as shown and specified, for thepurpose set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature 105
